Whenever Zed autoattacks an enemy below 50% health, he deals an additional percentage of their maximum health as magic damage. This effect cannot occur on the same target more than once every 10 seconds.

Active: Zed and his shadows throw their shurikens, each dealing physical damage to the first enemy they pass through and a lesser physical damage to enemies thereafter.
Living Shadow: Additional shurikens striking the same enemy deal 50% physical damage and restore energy.

Passive: Zed's bonus attack physical damage is increased by a percentage.
Active: Zed's shadow dashes forward, remaining in place for 4 seconds. Reactivating this ability will cause Zed to switch positions with this shadow.
Zed's shadow will mimic his basic abilities. If both strike the same target Zed regains some energy. Energy can only be restored once per mimicked ability.

Active: Zed and his shadows create a burst of shadow, dealing physical damage to nearby enemies. Each enemy champion hit reduces Living Shadow's cooldown by 2 seconds.
Living Shadow: Active shadows also slash, dealing physical damage to nearby enemies and slowing them for 1.5 seconds. Overlapping Shadow Slashes striking the same enemy deal no additional damage but will incur an increased slow and restore energy.

Active: Zed becomes untargetable and dashes to target enemy champion. Upon arrival, he marks the target for death and spawns a living shadow behind the target. This shadow lasts 6 seconds and mimics Zed's abilities. Reactivating Death Mark will cause Zed to switch positions with this shadow.
After 3 seconds, the mark will detonate, dealing physical damage equal to 100% of Zed's attack damage plus a percentage of all magic and physical damage dealt to the target by Zed and his shadows while the mark was active.
